The pain in the lower left segment of the abdomen in men can be caused by different reasons. Anatomically in this area, the sigmoid and rectum are projected. In addition, soreness can cause inflammation of the prostate gland, spleen, renal colic.

Disease of the intestinal tract

The pain in the lower abdomen on the left in men can be a sign of the following diseases:

  • proctosigmoiditis (proctitis);
  • sigmoiditis;
  • diverticulitis;
  • intestinal obstruction;
  • nonspecific ulcerative colitis;
  • polyps of the sigmoid colon;
  • Sigmoid / rectum cancer.

Proctosigmoiditis (proctitis)

Pain in the left side can cause a combination of inflammation of the mucosa of the rectus and sigmoid colon. Signs of the disease are:

  • pains in the lower abdomen on the left, giving to the perineal zone, the bladder area, buttocks and the front surface of the thigh;
  • frequent desires for defecation, accompanied by the allocation of a small amount of a crumbed stool containing blood and mucous inclusions;
  • dyspeptic disorder - diarrhea (constipation accompanies the disease much less often).

For the chronic form of sigmoiditis, mucus is secreted from the anus, which causes itching and irritation of the skin around the anus. The cause of the disease can be: infections of various origins, in particular, dysentery, typhoid fever, as well as syphilis and gonorrhea, constipation - particles of dried stool cause irritation of the intestinal walls, allergic reaction.

After diagnosing the cause of inflammation of the intestine, the man is prescribed the appropriate therapy.


Sigmoiditis is an inflammation of the sigmoid colon, which proceeds in acute and chronic form. Most often is a combined lesion of the sigmoid and rectum. In this case, the rectosigmoiditis is diagnosed. Sometimes the clinical picture of sigmoiditis is traced in colitis - inflammation of the large intestine.

Sigmoiditis is one of the causes of soreness in the lower left part of the abdomen in men

There are several varieties of sigmoidite:

  • Catarrhal. In the inflammatory process, only the surface layer of the intestinal mucosa is involved. The condition is accompanied by the release of a small amount of mucus.
  • Erosive. On the surface of the mucosa are formed erosive areas that do not affect the deep layers of the mucosa.
  • Ulcerative. On the surface of the mucosa there are deep ulcers.
  • Pericigmoiditis. Inflammation extends to the serous membrane, which causes the formation of infiltrates around the intestine of various sizes. The mesentery is involved in the pathological process. Formation of adhesions occurs.

Symptoms of sigmoiditis include the following manifestations: sharp cramping pains in the left half of the abdomen, extending to the left leg and into the lumbar region, nausea, vomiting, bloating, upset of the stool (diarrhea), combined with frequent false urges - stinking stench containing blood and mucus (it reminds me of meat slops).

Appears only a mixture of mucus and blood without particles of stool, intoxication - headache, weakness, weakness, increased body temperature. Treatment of the disease is conservative. The patient is prescribed adherence to the therapeutic diet, as well as taking antibiotics and probiotics to restore the intestinal microflora.

Sigmoid diverticula

Soreness in the left side of the lower abdomen on the left may be a symptom of sigmoid colon diverticulitis. The disease is accompanied by the development of pathological protrusions in the walls of the intestine, and is one of the most frequently diagnosed gastrointestinal pathologies.

The causes of diverticulum formation are: changes in the walls of the intestine of a dystrophic character, disturbances of intestinal peristalsis, stagnation of fecal masses in the lumen of the sigmoid colon, vascular pathology of the gastrointestinal tract. Most often these factors work in combination.

The period of exacerbation of diverticulitis is accompanied by the following symptoms:

  • acute / cramping, sometimes aching pain from below the abdomen;
  • frequent constipation;
  • bloating;
  • heaviness in the abdomen, decreasing after the act of defecation;
  • nausea, resulting in vomiting;
  • the presence of impurities in the feces of the blood;
  • increased body temperature;
  • general malaise.

Treatment of the disease is complex and includes several points:

  • Reception of medicines. A man is prescribed drugs from the category of antibacterial drugs, antispasmodics, laxatives, prokinetics and enzymes.
  • Compliance with medical diet.
In severe cases, a surgical operation is prescribed.

Bowel obstruction

Sometimes the left side hurts in the lower abdomen of a man due to intestinal obstruction. This pathological condition arises from the presence of mechanical / functional reasons that prevent the passage of food and fluid through the large intestine.

The main signs of colon obstruction include: spasmodic pain localized to the left in the lower abdomen, attacks of nausea, resulting in vomiting, severe asymmetric bloating, constipation, delayed gases.

Causes of drawing pains in the lower abdomen

A typical clinical picture develops against a background of complete well-being. The first symptom is severe pain in the left lower abdomen.

Initially, it is determined in a specific place, and then, as the condition worsens, it becomes diffuse.

The patient feels strong contractions of the intestine, accompanied by active bubbling. As the pathology progresses, the condition of a person worsens greatly: the patient pales, he has a significant sweating.

The absence of an adequate state of treatment may pose a threat to human life. Against the background of obstruction, necrosis of the affected part of the intestine, caused by a violation of the local circulation, is not ruled out. In the future there is perforation of the intestine and development of peritonitis.

Nonspecific ulcerative colitis

Nonspecific ulcerative colitis is a diffusely ulcerative inflammation of the mucous membrane of the large intestine. The origin of the disease has an unclear etiology. The reasons for its development can be:

  • viruses and bacteria;
  • violations of the autoimmune nature.

Nonspecific ulcerative colitis is characterized by undulating course: persistent remission is replaced by exacerbations.

Crohn's disease and ulcerative colitis
Comprehensive examination is necessary for the differentiation of pathology

Symptoms of pathology in the acute period are:

  • bleeding from the anus;
  • painful tenesmus;
  • pulling pains in the lower abdomen;
  • frequent diarrhea;
  • fecal masses contain impurities of blood.

Nonspecific ulcerative colitis is characterized by weight loss, which is due to a decrease in appetite, impaired digestion and frequent liquid stool. A special danger for humans is the fulminant form of pathology, which develops lightning fast. Her severe complications are perforation of the intestinal wall and its toxic increase.

Since the reasons for the development of pathology to doctors are not completely known, the therapy is reduced to reducing inflammation, reducing pathological symptoms and preventing exacerbation. Treatment involves the use of therapeutic and surgical techniques. An important point is the observance of the therapeutic diet.

Polyps of the sigmoid colon

The cause of pain can become polyps, growing from the tissues of the glandular epithelium and directed into the intestinal lumen. They may look like mushroom-shaped, grooved or spherical formations, which are attached to the surface by a mucus with the help of a pedicle. Initially, they are benign, but tend to be reborn.

There are the following varieties of polyps:

  • Hyperplastic. The most frequently diagnosed tumors resemble flat round plaques. Turn into a cancerous condition is rare.
  • Adenomatous. Are prone to degeneration and belong to precancerous conditions. At the very beginning of development they do not declare themselves about themselves. As they grow, they can cause intestinal obstruction and frequent bleeding.
  • Diffuse. The causes of their formation are hereditary diseases.

The causes of the formation of polyps are: chronic pathology of the gastrointestinal tract - diverticulitis, Crohn's disease, ulcerative colitis, intestinal dysbiosis, predisposition at the genetic level, insufficient physical activity, low fiber content in consumed food.

Symptoms of polyps of the sigmoid colon become (clinical symptoms appear late and only after the size of the polyp exceeds 3 cm):

  • when trying to sit down or make any sudden movement the patient experiences severe soreness in the lower left segment of the abdomen;
  • the presence in the stool of the veins of fresh blood, which is explained by the trauma of the villous polyps;
  • a large amount of mucus in the feces indicates the presence of glandular polyposis;
  • alternation of constipation and diarrhea;
  • false desires for defecation;
  • bloating caused by increased flatulence;
  • frequent heartburn and belching.

Polyps of the sigmoid colon for a long time are asymptomatic
The last stages of polyposis are characterized by worsening of the patient's condition: intestinal obstruction develops, fatigue increases, body temperature increases.

Diseases of the spleen

The causes of pain can be the pathology of the spleen. The pain in the lower abdomen on the left can be accompanied by: abnormal organ enlargement, spleen infarction, abscess, vomiting, myelo- and lymphocytic leukemia.

Expansion of the spleen

The organ is located in the region of the left hypochondrium, but as a result of abnormal expansion of the pain appear along the lower abdomen (its left side). The causes of inflammation can be inflammatory process, worsening of blood circulation in the organ.

Signs of pathology are:

  • painful spasms of the intestine, felt below the left;
  • attacks of nausea, resulting in vomiting;
  • increase in overall body temperature.

Spleen infarction

The infarction is caused by the overlap of the lumen of the artery feeding the spleen. In this case, the death of a part of the organ occurs. Signs of the occurred heart attack are: a sharp pain, descending their left hypochondria down the abdomen, intensifying the pain syndrome with deep inspiration, movement, coughing, raising the body temperature to high levels.

Abscess of the spleen

Strong pain accompanied by the formation of abscesses. The symptomatology of the condition is as follows: spasmodic pains in the left hypochondrium, extending to the left part of the thorax and lower abdomen, intensifying weakness, fever, nausea, resulting in vomiting.

Abscess of the spleen
The condition requires surgical intervention and the appointment of antibiotic therapy

Sphere of the spleen

The cause of the condition is the twisting of the artery, which supplies the spleen with blood. A defect caused can be a trauma to the ligaments of the mesentery or their congenital pathology. Symptoms of the pathology may include: bloating, constipation, pain, descending from the left hypochondrium to the abdomen, vomiting, gradual deterioration of the condition.

Myelo- and lymphocytic leukemia

Soreness develops after eating and when you click on the area of ​​the projection of the spleen. As the condition worsens, soreness will only increase.

Gastritis or gastroduodenitis

Stomach with inflammation can significantly increase in size, sinking into the lower calving of the abdomen. In such cases gastritis is accompanied by strong intestinal cramps. Additional signs of pathology are:

  • nausea;
  • bouts of heartburn;
  • Stitching pain when pressing on the epigastric region.

Atypical location of an inflamed vermiform appendix

With appendicitis, soreness is most often determined on the right, but in rare cases pain is shifted to the left. Symptoms of a pathological condition are:

  • Initially, moderate intestinal cramps, which increase with time - the pain becomes cramping, pulsating;
  • nausea, resulting in vomiting;
  • diarrhea (relatively rare);
  • fever.

The soreness of the lower left abdomen in men may indicate the development of serious illnesses. And with the appearance of pathological symptoms it is recommended to get a qualified medical consultation.
